UnibondGrout Reviver Pen, White Grout Pen for Bathroom Grout Joints, Easy to Use Tile Grout Pen, Whitener for Restoring Discoloured & Faded Joints, 1x7ml

Did the job. Got 3 just in case as some say it emptying fast but I manage to do all bathroom with just one.

This worked well and even after washing the shower the next day with cif cream cleaner the grout stayed nice and white.Only negative is that the tip that needs to be pushed in several times to load up with the white liquid gets ruined easily. So despite there being lots of liquid left to paint the gout with, the nip won't push in anymore because it has frayed apart and no longer functions. So there was enough white liquid to complete the shower but I had to order a second one to finish the job.

This unibond 7ml grout pen is a great product & certainly revives things well to nice & crisp white. Told that it is easy to apply & that you can be more precise with it being pen & that there is no need to press too firmly & that it quickly dries within 60 minutes. & a tip the nip needs to depressed quiet a few times until the product flows you can think this isn’t working got a dud it just takes a while to come through. & when the nib frays pull it out & use the other end. & that a good thing is if any mishaps or have applied too much you can simply remove it with a damp cloth. This grout pen is great to restore discoloured grout & revive dull areas. Ours is used around the toilet because it goes off white quickly & odd tiles the white grout, a great product that saves you money & the need of replacing the grout in e.g bathroom/kitchen & so on.

The UniBond Grout Reviver Pen is a simple and easy-to-use product designed to refresh discolored grout, giving tiled surfaces a cleaner and brighter look. While it’s a handy tool for minor touch-ups, it may not be a long-term solution for heavily stained or deteriorated grout.Pros:✅ Quick and Easy Application – The pen-style design makes it convenient to apply without the mess of traditional grout.✅ Instant Brightening Effect – Works well on lightly stained or faded grout, providing a whiter and fresher appearance.✅ No Strong Odor – Unlike some grout paints or sealers, this pen has minimal odor, making it more pleasant to use indoors.Cons:❌ Not Ideal for Deep Stains or Heavy Wear – While effective for surface-level discoloration, it may not fully cover deeper stains or fix cracked/damaged grout.❌ May Require Multiple Coats – Depending on the grout’s condition, more than one application may be needed for an even finish.❌ Durability Varies – The effect is not long-lasting in high-moisture areas like showers, where it can fade over time.Verdict: A Handy Touch-Up Tool, but Not a Permanent FixThe UniBond Grout Reviver Pen is a useful, budget-friendly option for quickly refreshing grout in kitchens and bathrooms. However, for deep stains, worn-out grout, or long-term results, re-grouting or using a more durable grout paint might be a better choice.⭐⭐⭐ (3/5) – Good for quick fixes, but not a lasting solution for heavily stained grout.

Works well

Waste of money within 10 mins of using this the nib split and separated , turned it over managed to swap ends but then the nib went in and now can’t use it . Don’t waste your money !!

Brilliant, easy to use and easy to clean afterwards, grouting looks brilliant.

Good, need a steady hand! also half the price of the shops!!
